Botanical classification rosa hybrid variety denomination &#39;poulpar041&#39;

ABSTRACT

A new miniature rose plant that has abundant, pink apricot blend flowers and attractive foliage. The variety successfully propagates from softwood cuttings and is suitable for year-round production in commercial glasshouses. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

BOTANICAL CLASSIFICATION

Rosa hybrid

VARIETY DENOMINATION

‘Poulpar041’

SUMMARY OF THE INVENTION

The present invention constitutes a new and distinct variety of miniature rose plant which originated from a controlled crossing between the female seed parent, an unnamed seedling, and the male pollen parent, ‘Korkleiva’ described and illustrated in U.S. Plant Pat. No. 11,232. The two parents were crossed, and the resulting seeds were planted in a controlled environment. The new variety is named ‘Poulpar041’.

The new variety may be distinguished from its seed parent by the following combination of characteristics:

-   -   1. ‘Poulpar041’ has a flower diameter of 35 to 40 mm while the         pollen parent has a smaller diameter of 25 to 30 mm.     -   2. ‘Poulpar041’ has pink apricot blend flowers while the pollen         parent has near white flowers.

The new rose may be distinguished from its pollen parent ‘Korkleiva’ by the following combination of characteristics:

-   -   1. ‘Poulpar041’ has normally 35 flower petals, 10 to 13 of which         are petaloids. ‘KORklevia’ has 25 to 30 flower petals.     -   2. Flower diameter of ‘Poulpar041’ is 35 to 40 mm, while         ‘Korklevia’ is 38 to 44 mm.

The objective of the hybridization of this rose variety for commercial culture was to create a new and distinct variety with unique qualities, such as:

-   -   1. Uniform and abundant pink apricot blend flowers;     -   2. Vigorous and compact growth;     -   3. Year-round flowering under glasshouse conditions;     -   4. Suitability for production from softwood cuttings in 10 to 15         cm pots;     -   5. Durable flowers and foliage which make a variety suitable for         distribution in the floral industry.

This combination of qualities is not present in previously available commercial cultivars of this type, known to the inventor, and distinguish ‘Poulpar041’ from all other varieties of which we are aware.

As part of the rose development program, Mogens N. Olesen germinated the seeds from the aforementioned hybridization and conducted evaluations on the resulting seedlings in a controlled environment in Fredensborg, Denmark.

‘Poulpar041’ was selected by the inventor as a single plant from the progeny of the hybridization in June 2002.

Asexual reproduction of ‘Poulpar041’ by cuttings and traditional budding was first done by Mogens N. Olesen in the nursery in Fredensborg, Denmark in April 2003. This initial and other subsequent propagations conducted in controlled environments have demonstrated that the characteristics of ‘Poulpar041’ are true to type and are transmitted from one generation to the next.

1. A new and distinct variety of rose plant of the miniature class named ‘Poulpar041’, substantially as illustrated and described herein, due to its abundant, pink apricot blend flowers, vigorous growth, compact habit, suitability for production from softwood cuttings in small pots, and durable flowers and foliage that make the variety suitable for distribution in the floral industry.
